According to reports in Autosport, the Mercedes grand prix team will arrive at the Barcelona circuit next weekend with a new package for their 2010 contender in the hope that it will help fix the weight distribution issues they have been struggling with all season.

The new package will consist of a major aero upgrade including a longer wheelbase that should help with the way the 2010 tyres operate and the understeering issues that seven time world champion Michael Schumacher has been encountering all season.

"The problem is not actually the wheelbase per se, it is the weight distribution," team boss Ross Brawn was quoted as saying by Autosport. "We got the weight distribution wrong. When we got to test these tyres we realised we didn't have the correct weight distribution and we went to the limit with what we could achieve with this car. It is not the wheelbase as such, it is the weight distribution that is not what we wanted it.”

"The tyres changed quite a bit... and we didn't have the opportunity to test these tyres, and we didn't have as good a guess of what was required as some of the other teams. So we will have a modification to the car at Barcelona which will give us a better range for the weight distribution that we can achieve."
